1. Employer Contributions and Vesting
It’s not enough to divide the full balance of a 401(k). You must factor in vesting schedules. Employer contributions are often subject to vesting—that means the participant may only be entitled to a portion of the employer money depending on their service duration. If the division is based on the entire account but the participant isn’t fully vested, the alternate payee could receive less than expected.
To manage this, the QDRO should include language that either:
- Excludes non-vested amounts, or
- Requires reallocation from the participant’s share if funds were over-awarded
